Product features:
Curing agent sf-paa is an excellent epoxy resin curing agent modified by Mannich condensation reaction with phenol and formaldehyde with polybasic primary amine as the main raw material. Condensation compounds containing phenolic hydroxyl (- OH), primary amino (- NH2) and secondary amino (- NH -) in molecular structure have high reaction activity and fast curing speed, and can be cured rapidly at room and low temperature; Low viscosity and easy operation; The system changes the disadvantages of poor toughness and brittleness of the traditional phenolic amine curing system. The cured product maintains superior strength and has superior mechanical properties.

Product technical indicators:
Note: 1 The reference dosage is only for reference, and the actual dosage is subject to the formula;
2. Gel time is tested in the laboratory only for customer reference, not as a quality indicator.
Application field and instructions:
1. It is mainly used to prepare epoxy adhesive, sealant, coating, anti-corrosion, casting and laminating materials. Cooperating with epoxy resin, it can be used as adhesive, anti-corrosion in chemical industry, civil construction, coating and FRP industry, anti-corrosion of equipment and pipeline, adhesive and RE modification, and can be used for sealing and potting of low-voltage electronic components, intermediate and primer coating and decoration of epoxy floor, highway pavement repair {and building structure adhesive, etc;
2. Surface treatment: the oil stain, dust, rust, etc. on the contact surface of the adhesive must be cleaned;
3. Good curing effect can be obtained by adding phenolic amine series epoxy curing agent with a certain proportion of epoxy resin weight at room temperature;
4. The dosage can be appropriately increased in low temperature and humid environment;
5. Some fillers can be added as required, such as quartz powder, silicon micro powder, titanium dioxide, talc powder, mica powder, etc.
Packaging, transportation and storage:
1. Use clean 25 kg plastic bucket and 200 kg plastic bucket Plastic barrel packaging; Rain and sun protection shall be provided during transportation to prevent package damage and moisture;
2. Store under cool and dry conditions, away from fire source, strong acid, strong alkali and strong oxidant;
3. Under the transportation and storage conditions conforming to the standards, the storage period is 12 months from the date of production.
