Applications
 |
Paper, paperboard and other cellulosics, glass, metals and foils, polyamides, polyethylene, polyurethane, and rubber . . . PRIMACOR* copolymers can be modified to fit almost any application area based on your specific requirements. Here are a few possibilities:
|
Metals
|
|
PRIMACOR copolymers form strong, lasting bonds with metals. Bond strengths to metals whose corresponding oxide layers are well-adhered (such as aluminum and tin) exhibit good resistance to moisture. In contrast, copper has a weakly bound oxide layer; therefore, coatings of PRIMACOR copolymers on copper will form water-sensitive bonds that could be limiting in some applications.
|
|
Glass
|
As a polar material, glass is a substrate to which PRIMACOR copolymers readily adhere, making it an excellent option for glass coatings or laminations.
|
|
Cellulosics & Natural Substrates
|
Hydrogen bonding of PRIMACOR copolymers to cellulose, wood pulp, leather, natural fibers, cellophane, proteins, and similar natural substrates is excellent.
|
|
Plastics
|
While the carboxyl groups readily enter into hydrogen bonding interactions with polar groups such as metals, glass, cellulose, polyamides, and polyurethanes, they also form very good bonds with plastics such as polyethylene and ethylene propylene dien monomer (EPDM, or "rubber").
|
| Itself |
The molecular design of PRIMACOR copolymers allows for exceptional thermal welding. Strong bonds of the polymer to itself, much like a chain welded at the link, are possible across a wide range of temperatures. |
| Other |
What are your requirements? The polar functionality of PRIMACOR copolymers creates remarkable adhesive characteristics. Together, the potential of high adhesion with the convenience of a thermoplastic, provide imaginative innovators a truly promising and opportunistic resin. |
