Coating classification: alkali resistant sealing primer

Core tip: composition of alkali resistant sealing primer Alkali resistant sealing primer is composed of alkali resistant resin, wear-resistant filler, solvent, auxiliary agent, etc Main characteristics of alkali resistant sealing primer The anti alkali sealing primer coating has strong adhesion to concrete, outstanding alkali resistance and sealing performance, and good compatibility with a variety of floor coatings and protective coatings for concrete structures Application of alkali resistant sealing primer Alkali resistant sealing primer is used as protective sealing primer for concrete substrate (1) Close the substrate, penetrate into the internal structure of the substrate, block the pores in the substrate, reduce the number of open pores in the substrate, and increase the number of closed pores, Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Home of coatings: alkali resistant sealing primer is composed of alkali resistant resin, wear-resistant filler, solvent, additives, etc The main characteristics of alkali resistant sealer are the strong adhesion of alkali resistant sealer coating to concrete, outstanding alkali resistance and sealing performance, and good compatibility with a variety of floor coatings and protective coatings for concrete structures Alkali resistant sealing primer application alkali resistant sealing primer is used for concrete base material as protective sealing primer (1) Seal the substrate, penetrate into the internal structure of the substrate, block the pores in the substrate, reduce the number of open pores in the substrate, increase the number of closed pores, inhibit the penetration of coating water, make the penetration uniform, and make the absorption of the substrate to the upper coating uniform (2) The sealing primer can prevent moisture, resist alkali isolation, effectively isolate the alkali of the base layer, and prevent the alkali from seeping out and damaging the coating (3) Strengthen the loose and weak basement to strengthen the basement Technical index of alkali resistant sealing primer: adhesion, grade ≤ 2 impact strength, kg · cm50 salt water resistance (3% NaCl, 25 ℃, 96hr), no foaming, no rust, no falling off, dry film thickness 25m m theoretical dosage 120g / M flash point 38 ℃ drying time of alkali resistant sealing primer 25 ℃ 0.5h, 24h recoating interval: the shortest temperature is 25 ℃ 4H 7d Construction description of alkali resistant sealing primer surface treatment: the concrete foundation must be cured for more than 28 days with moisture content less than 8% Mixing ratio: single component coating, which can be used after being fully stirred and packed Limitation: unlimited requirements for construction environment Coating method: Airless Spraying: nozzle diameter: 0.4-0.5mm air spraying: nozzle diameter: 2.0-3.0mm spray pressure: 0.3-0.5mpa diluent: xc102 dilution: 0-10% (by coating weight) roll coating and brush coating: diluent: xc102 dilution: 0-3% (by coating weight) coating family is focused on coating, diatom mud, paint coating, coating process, News and information of fire retardant coating, coating, diatom mud, paint coating, coating technology, decoration knowledge and decoration effect map of fire retardant coating,
