High temperature solvent - resistant vinyl ester resin
SWANCOR 977-S is a high-performance modified Novolac type epoxy vinyl ester resin with high crosslinking density and excellent solvent resistance, such as EDC, DMF, chlorobenzene, benzene and other highly soluble solvents. It also has excellent high temperature resistance, and still has good performance at 200℃. It also combines excellent mechanical properties such as tensile and bending strength at high temperatures. SWANCOR 977-S has excellent chemical resistance and is suitable for dichloroethylene (EDC), dimethylformamide (DMF), benzene, toluene and ketone.
SWANCOR 977-S packaging, storage and operation
1. SWANCOR 977-S comes in 55 gallon iron drums weighing 200 kg and 5 gallon iron drums weighing 20 kg.
2. SWANCOR 977-S is a reactive resin and should be stored in a cool place. If it is stored for too long, the bottle can be opened
Air is injected into the lid to extend its storage time.
3. The gelation time of SWANCOR 977-S is mainly affected by the content of accelerators and the concentration of hardener by temperature, due to
Differences in hardeners, humidity, pigment fillers and other additives can all affect the hardening properties, so they are recommended
When this product, the operator had better test the hardening characteristics in a small amount first under the operating conditions set by oneself.
