** The optimum level of catalyst should be deter mined experimentally for each particular end-use. Safety Infor mation Material Safety Data Sheets (MSDS) are available for all Rohm and Haas products. These sheets contain important information that you may need to protect your employees and customers against any known health and safety hazards associated with our products. We recommend that you obtain copies of our MSDS from your local Rohm and Haas technical representative before using our products in your facilities. We also suggest that you contact your suppliers of other materials recommended for use with our products for appropriate health and safety precautions before using them.
Pr ocessing ADCOTE 122 HV-E+Catalyst 9L10 can be applied at a solids content of 30-35%. Application can be done by using reverse roll coater or smooth roll coater/knife systems. Methyl Ethyl Ketone (MEK), Acetone or Ethyl Acetate (EA), with a maximum water content of 0.2%, are suitable as diluents. Aliphatic solvents, alcohols or alcohol containing solvents must not be used. 

# ADCOTETM 122 HV-E+CATALYST 9L10

ADCOTE 122 HV-E+CATALYST 9L10 11/2005 Page 1 of 2 Description ADCOTE 122 HV-E is the modified polyester basic component of a two-component specific performance laminating adhesive system which requires the use of an isocyanate coreactant. The full cured adhesive provides a combination of features and benefits : -good initial bond properties; -long-term high temperature resistance under specific high stress levels; -specific high bond strength values; -good chemical and humidity resistance; -excellent UV resistance. Application When mixed with Catalyst 9L10 (or other isocyanate coreactants*), the resulting polyurethane adhesive is suitable for a range of specific demand applications in the manufacturing of technical laminates such as : -Sailcloth laminates; -UV -resistance laminates; -T

emperature-resistant laminates.
Suitable web materials : -Polyester (PET and PEN) films and fabrics; -Textile fabrics like cotton, wool, linen, etc.; -Metal foils (aluminium, etc.); -Polyolefine films (pre-treated).
An inter-reaction between the adhesive and the other constituents of the laminated structure like printing inks, films, additives and coatings may occur. Besides the desired effects, these inter-reactions may also lead to unforeseeable changes in quality

. Therefore, before regular production, the suitability of the adhesive for the structure to be produced and intended applications must be proven by practice test.

Application Weight Enough wet adhesive should be applied to reach a dry adhesive layer of 6-15 g/m 2 (depending on the used web material and the required end-use performance). Drying The coated substrate has to pass through a drying tunnel to remove completely the remaining solvents in the adhesive film. In order to reach this, the temperature and the line speed have to be adjusted. Normally this will be done in a range of 20 seconds at 60-100°C. Nip Temperature After leaving the drying tunnel, the web material to be laminated must be nipped at a minimum temperature of 65 °C (depending on the used materials) in order to reach a minimum temperature of 60°C in the glue line.
A

void film stress, this will give problems when the adhesive is cured.
Pot Life The pot life of ADCOTE 122 HV -E+Catalyst 9L10 is approximately 8 hours at 35% of solids content. It can vary based on environmental temperature and humidity conditions. Curing Time Machinable bonds develop within 2-3 days at room temperature. Curing begins during lamination and continues slowly at room temperature. Several days will be necessary to complete the cure at room temperature (depending upon the laminate structure) but post-cure at elevated temperatures can reduce this time. Cleaning
A proper cleaning procedure should be considered and implemented as a part of machine operation. After finishing work the equipment should be cleaned immediately with MEK or EA. Storage and Shelf Life The expiry date of ADCOTE 122 HV-E+Catalyst 9L10 has to be considered the one reported on the label of the package. This data is valid if the product is stored in a dr y and cool place (5-25 ° C) in closed original containers.
