Scotch-Grip™
Plastic Adhesive 2262
Scotch-Grip Adhesive 2262 can be a useful primer when thinned in acetone in a 1:5 or
1:10 ratio (e.g., 1 part Scotch-Grip Adhesive 2262 to 5 parts solvent). This will work
especially well for plasticized vinyl film. Dries quickly, can be wiped or brush applied.
This thinned material contains 196 g/l VOC’s when diluted in these ratios.
Note: When working with solvents, primers, or other chemicals be sure to read the
manufacturer’s precautions and directions for use when handling such materials.
Diluted 3M™
Scotch-Grip™
Plastic Adhesive 1099
Scotch-Grip Adhesive 1099 can be useful as a primer for elastomeric materials when
thinned in acetone in a 1:3 ratio (e.g., 1 part Scotch-Grip Adhesive 1099 to 3 parts
acetone). This solution dries quickly and can be wiped or brush applied. This thinned
material contains zero VOC’s when diluted in these ratios.
Note: When working with solvents, primers, or other chemicals be sure to read the
manufacturer’s precautions and directions for use when handling such materials.
3M™ Tape Primer 94
3M Primer 94 has been developed to help promote adhesion to a wide variety of
substrates. Careful evaluation is suggested to ensure performance is adequate for a
particular use and application method.
