ADCOTETM 1025 

Solution Coating 

Description

Adcote 1025, a solution coating based on Mor-Ester® 49000 polyester resin, is available in two solvent 

systems. It provides excellent adhesion to most plastic and metal surfaces, and can be used as a primer, 

heat seal coating, binding resin or ink vehicle base. 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. Alcohols and similar materials containing active hydrogen can react with Adcote 1025 resin, 

causing inadequate cure. Adcote 1025 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 1025 resin. 

General Information

The initial color and clarity of Adcote 1025 resin will remain unchanged after outdooor exposure. In addition, 

Adcote 1025 resin is resistant to dilute acid and alkali solutions. When Adcote 1025 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.

Directions For Use

Apply Adcote 1025 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. 

The preferred method for bonding is to 1.) coat the more stable substrate, 2) heat so the glue line is 270F 

minimum, and 3.) bond. 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 270F. 

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 can reduce this time. 

Pot Life

Do not mix more Adcote 1025 resin and coreactant that will be needed in 8 hours. Any mixed solution that 

is left over should be stored in tightly closed containers and used within 3 days. When reusing, we 

recommend combining the old mixed solution with the newly mixed solution at a ratio of 25% old/75% new. 

Mix thoroughly. 

Safety Precautions

Adcote 1025 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.
