Uses

Joint sealing at cleanrooms for production/processingof electronic devices such as semiconductors and ﬂat
displays and laboratories and at research facilities forevaluation of outgassing- Joint sealing of interior panels- Joint sealing around openings- Joint sealing around air-ﬁlters, penetrating
pipe, and pipe joints- Sealing around ﬁxture units of equipment

Features■Low outgassing
It generates no cyclic siloxane or generates, if any, an extremely small quantity of other organic gases.
It contains no DOP, DBP and other phthalic acid plasticizers or solvents.
It uses none of 13 volatile organic compounds (VOCs) that can cause sick-house syndrome as speciﬁed in Guidelines for Indoor Air Pollution ‒ Guideline values for indoor concentration by the Ministry of Health, Labor and Welfare.

■Excellent non-self-contamination characteristics
Once cured, it gets almost non-sticky. This will keep the beautiful surfaces
from being easily contaminated and spoiled after application.
Self-contamination: Adhesion of dust and other contaminants on the sealant surfaces due to stickiness of the sealant itself.

The sealants were applied at 20℃ or lower. At a speciﬁed time interval,
volcanic ash was sprinkled over the sealants, swept oﬀ with a brush,and the surfaces of the sealants were inspected for contamination.

■Excellent adherability without primers
It provides excellent adherability on most interior materials for cleanrooms.

■Excellent workability at low temperatures
Its low temperature-dependency provides stable extrusion characteristics in a wide range of temperatures.
Especially at low temperatures, its smooth extrusion capability will remarkably improve workability.

After use, the empty cartridge
may be compressed to
one-seventh the original size.

■Adoption of environmentally-friendly ECO-CART containeras dust-control and environmental measures in cleanrooms.
TheECO-CART

generates no dust, reducing 85% of waste as compared to a paper-core cartridge.

Organic Outgassing Characteristics

Dynamic Headspace Engineering Test Method

Organic outgassing sampling is conducted according to the Dynamic
Headspace Engineering Test Method as speciﬁed in the Guideline for Evaluationof Airborne Moleculer Contaminants Emitted from Construction / Composition
Materials for Cleanroom (Japan Air Cleaning Association, (JACA )).
<Conditions of Sample Curing>A stainless steel frame having one open plane (with the bottom raised by 10 mm using a stainless steel plate) is ﬁlled with the sample.
After application of the sample sealant, the frame is left exposed for 2 days in a room at a constant temperature and a humidity of 20℃and 60%, respectively. Then the test sample is wrapped in aluminum foil and cured for 26 days in the same condition.
(The measurement was conducted at the material age of four weeks)-6Fill in the sample of 6.0 x 10

Sample container: made of stainless steel

Purging gas (N2)TENAX GR sorbent tube

< Conditions of Sampling >The sample is placed in a micro-chamber of quartz cell (0f 0.9L in capacity) and theoutgas is collected in the Tenax sorbent tube while Nitrogen purging conducted.
● Purging gas ﬂow rate : 0.5L/min● Temperature / Humidity inside the chamber: 23℃, 45%< Conditions of Analysis >Oustgas analysis is conducted using TRANSDUCER-GC/MS (Thermal Desorption Gas Chromatograph/Mass Spectroscopy) and quantiﬁed through toluene conversion.

1) Remove moisture, oil, dust, rust and other contaminants from the joint or the joining surfaces and letthem dry.
2) Place masking tapes to mask oﬀ the areas thatshould not be contaminated.
3) Follow the steps as shown in the diagrams (Fig.1Fig.6) to attach the ECOCART to the cartridge gun.
4) Extrude an adequate quantity of the sealant to ﬁll inthe joint or the joining surfaces.
5) Flatten out to ﬁnish the sealant with a metal spatulaor a packer
6) Having ﬁnished it up, remove the masking tape immediately.

■The sealant is not applicable to glass materials exposed
to direct sunlight or ultraviolet light.
■In damp and wet conditions, the sealant can swell andcan be poor in adherability. Check that the substrates
are completely dry prior to application.
■The sealant hardens quickly. Apply the sealant as quickly
as possible in high temperature and humidity conditions.
■Adherability of the sealant can vary depending on substrates.
*Check for adherability beforehand when application of thesealant is planned on diﬃcult-to-adhere materials including antistatic paint- coated steel sheets, ﬂuoropolymer
paint-coated steel sheets, and ﬂuoropolymer paint-coatedaluminum. Apply the primer US-1 as necessary.
■Although the sealant basically provides excellent adherability
without primers, some substrates may require primers. For selection
and use of primers, consult the architect/designer beforehand.
■When application of the sealant is planned for maintenanceand repair of the existing sealant, check for adherability to theexisting sealant, or contact us. Avoid application to existingsilicon sealants, in particular, because adhesion is hopeless.
■Make sure the working area is well ventilated, especially when it is closed.
■Wash your hands thoroughly after application of the sealant.
■After application, the white color may turn yellow with time.
■Store the sealant in a dark and cold place (between 5℃ and25℃) while avoiding direct sun, ﬁre, moisture, or water.
■Use the sealant within the shelf life (within 12 months
after the manufacturing date).
■For disposal of ECOCART waste, let the content to harden andhave a licensed industrial waste disposal contractor handle it.
■For more detailed information, refer to the Material
Safety Data Sheet (MSDS).

irritation or inﬂammation occurs, immediately consult a doctor.
●In case the sealant gets into your eyes, rinse them thoroughly with cleanwater for at least 15 minutes and immediately consult an eye doctor.
●In case you inhale a lot of vapor of the sealant, move toa fresh-air area, rest while keeping yourself warm. Then
immediately consult a doctor.
●In case you ingest the sealant, rinse your mouth with water (andinduce vomiting if possible.) Then immediately consult a doctor.
●In case the sealant is splashed onto your clothes, try toremove it with a piece of cloth and wash it away withwater. Since it will be very diﬃcult to remove it
completely, be careful not to splash it.

●Penguin Clean Seal 2555 is produced to order.
Contact us for details.

* Application of the sealant requires aspeciﬁc ECOCART holder (optionallyavailable). This speciﬁc holder enables
application of the sealant with a generalpurpose cartridge gun (optionally available).
