ADCOTETM 49-196

Laminating Adhesive

Description

Adcote 49-196 is a solution adhesive based on Mor-EsterTM 49002PS polyester resin. It provides excellent 

adhesion to most plastic and metal surfaces, and can be used a primer, heat seal coating, or adhesive. This 

product's performance can be further enhanced by using recommended coreactants.

Precautions

See Material Safety Data Sheets for hazardous ingredients, flammability, disposal, and related handling 

information. Alcohol and similar materials containing active hydrogen can react with Adcote 49-196 resin, 

causing inadequate cure. Adcote 49-196 resin can react or interact with other components of the structure. 

Retained solvents, slip additives, anti-block agents, and contaminated solvents are some of the components 

that may cause property changes in substrates and/or Adcote 49-196 resin.

General Information

The initial color and clarity of Adcote 49-196 resin will remain unchanged after outdoor exposure. In addition, 

Adcote 49-196 resin is resistant to dilute acid and alkali solutions. When Adcote 49-196 is mixed with 

coreactant, its tensile strength and resistance to chemical plasticizers, solvents, and water are noticeably 

improved and its melting range increases. Also, with some substrates, the addition of a coreactant may 

improve adhesion.

High molecular weight polyesters that are used in solution adhesives like Adcote 49-196 have tendency to 

form a reversible structure in solution with time. This structuring is accelerated when the adhesive is 

exposed to temperatures below 50°F. The structuring is reversible if heat and shear is applied to the 

adhesive. We recommend placing the container of adhesive in a steam cabinet, allowing venting of the 

container and heating to 110-140°F. After the adhesive reaches the proper temperature, mix the adhesive 

in the container for 1-3 hours under moderate shear. Use of a disperser or “Cowles” type blade will 

shorten the time needed.

Caution must be taken because of the flammability of the solvents used in the adhesive. Please 

review MSDS for hazards associated with the adhesive.

Attempting to redisperse without heat may reduce the apparent viscosity, but not result in a 

homogeneous mix. Before using the adhesive, check, to make sure that all resin has returned to a true 

solution and no gels remain.

Directions For Use

Apply Adcote 49-196 resin using any of the conventional methods, including gravure coater, reverse roll 

coater, knife and spraying. Dilution may be necessary. Apply enough wet coating to deposit 0.1-0.3 dry mils 

(or approximately 2-6 dry lbs/3000 sq ft) and completely remove the solvents. Laminate with heated nip rolls 

to provide a minimum glue line temperature of 310F.

The preferred method for bonding is to:

1. Coat the more stable substrate.

2. Heat so that the glue line is 310F.

3. Laminate.

A heated press can be used for general purpose bonding by employing enough pressure to ensure intimate 

contact between the adhesive and both surfaces, and holding this pressure until the glue line reaches 310F.

When using Coreactant F, use the amount shown in the Typical Properties section as a guide. The optimum 

level of coreactant should be determined experimentally for each particular end use. Coating with coreactant 

is handled in the same manner as coating without coreactant. Curing begins after solvent removal and 

continues slowly at room temperature. Approximately 7-14 days are needed to complete the cure at room 

temperature, but a post cure at elevated temperatures (120°F) can reduce this time.

Pot Life

Do not mix more Adcote 49-196 resin and coreactant than will be needed in 8 hours. The mixture will react 

and increase in viscosity changing the way the materials coats, etc.

Safety Precautions

Adcote 49-196 resin contains somewhat toxic and/or flammable solvents, and suitable handling precautions 

should be observed. Do not inhale the fumes. Avoid prolonged and repeated skin contact. Eye contact 

must be prevented. Wear synthetic gloves, face shields, and aprons impermeable to these solvents 

whenever there is a possibility of skin contact. Use NIOSH approved respirators to avoid fumes.
