Product Description

Product Description

SP297 is a solvent-free, high-performance two-component polyurethane potting adhesive. The resin part (component A) contains hydroxyl groups, and the curing agent (component B) is based on isocyanate. After mixing, A and B are cured to form an elastomer with no significant volume change. It can be cured between 15-65 degrees without bubbles, with high volume resistivity and flame retardant grade UL94 V-0.

Key Features:

1.Comply with ROSH and REACH;

2.Thermal conductivity, flame retardant, CTI value ≥ 600;

3.Curing method: room temperature curing or 65ºC-30min for complete curing.

Typical Applications:

1.Filling, coating, casting, good bonding between metal and plastic;

2.Communication equipment, transformers, control power supplies, ignition controllers, electronic sensors, etc.;

3.Charging pile potting, potting of small and medium-sized electronic components, such as sensors, LED waterproof power supplies, mutual inductors, etc.

Packing and Storage:
Part A: 25kg/bucket
Part B: 6kg/bucket

Part A: 12 months
Part B: 9 months
In unopened packaging in a cool and dry storage place at temperatures between 8ºC to 28ºC.
