A Two-component Polyurethane Adhesive

1. Characteristicsi
A Two-component Polyurethane Adhesive is two-component room temperature curing high strength adhesive which is good at bonding a variety of metals, non-metallic materials .The product has a non-toxic, tasteless, non-polluting, oil resistance, high temperature resistance, impact resistance, fast curing time, high adhesive strength. Applies to the bond between the oil filter, diesel filter, industrial filters and air filter paper (non-woven) with metal, the product is suitable for mechanical injecting.

3.Construction operation
1, A and B component glue pump respectively into the classifies the glue tank, A stirring device is installed components.
2, To degrease and de-rust before gluing.
3, Mix A and B component glue according to the weight ratio of fully mixing.
4, The mixed colloid in 20 to 30 seconds glued object by injecting nozzle uniform injection.
5, Five minutes to the filter paper and glued object alignment after flat joint.
6, Adhesive 20-30 minutes into the next process.
