Product Usage:
102A can react with aliphatic amines and aromatic amines at normal temperature, and with hydroxy compounds and nylon at medium and high temperatures. It is mainly used in epoxy resin coatings and adhesives to form epoxy-polyurethane interpenetrating polymer networks or islands after curing. The structure can improve the flexibility of the material, increase the shear strength, adhesion, tensile strength, flexural strength, etc. of the adhesive layer, and has less influence on the heat resistance of the composite material. It can also be cured directly at normal or medium temperature with fatty amines or aromatic amines to obtain elastomers with superior properties.
102B can react with fatty amines, aromatic amines, hydroxy compounds, nylon, etc. at medium and high temperatures; it is mainly used in epoxy resin coatings and adhesives to form epoxy resins (phenolic resins, polyesters, etc.)-Polyurethane interpenetrating polymers after curing. The network or sea-island structure can improve the flexibility of the material, increase the shear strength, adhesion, tensile strength, flexural strength, etc. of the adhesive layer, and have less influence on the heat resistance of the composite material. It can also be cured directly at medium and high temperatures with fatty amines or aromatic amines to obtain elastomers with superior properties.
Usage and dosage:
When used as a toughener, the amount of epoxy resin is generally 10-30%, and the amount of curing agent should be increased accordingly. When used for elastic glue, the amount is generally 300% of epoxy resin.
This product can be added to epoxy resin or amine curing agent; 102A-1, 102A-2, 102B-1 is added to amine curing agent when it is used at room temperature for 7 days or 60 degrees and 4 hours before use. Use the curing agent at 80 ° C for 4 hours.
Product packaging and storage: 桶, 20 KG /桶,210Kg/桶。 2 KG / barrel, 20 KG / barrel, 210Kg / barrel. Keep it tightly closed, and prevent water vapor from entering. Shelf life is 25 ℃ * 12 months.
