"EVA multi-function elastic waterproof coating" is a new and effective waterproof materials, construction ministry expert thinks: The material for Chinese waterproof materials added a new varieties, its main technical index has reached the developed countries similar product level.
Its main technical indices (7 days)
(1) tensile strength: Greater than 1.65 MPa,
(2): Greater than 250% elongation,
(3) the low temperature flexible: - 10 ~ 20; ; -
(4) bond strength: Greater than 1.0 MPa,
(5) water impermeability: 1.3 MPa 30min; Not leak.
(6) high temperature resistant: 120;
(7) solid content: P 65%,
Main features:
(1) can be in wet or dry many kinds of material base surface construction;
(2) avirulent, harmless, free from contamination, belong to environmental protection waterproof materials, and can be used for drinking water project,
(3) construction safety, simple and short time,
(4) coating high strength, high elastic, water resistance, excellent weatherability,
(5) with base surface and cement mortar, etc. Various kinds of outer material firm bonding, eliminating the waterproofing materials empty drum defects,
(6) can add pigment, in order to form colour coating, beautify the environment,
(7) overall continuous constantly waterproof layer, no juncture, not easy leakage,
(8) adiabatic, anti-ultraviolet radiation, anti aging.
(9) with respiratory function, can prevent boom share in walls and roofs accumulation.
Application:
But in wet or dry bricky stone, concrete, metal, mortar, the insulation layer and other kinds of various waterproof layer (for example, SBS asphalt APP, polyurethane and so on) direct construction, for house (roofing, underground, outer wall, lavatory bath rooms etc), tunnels, Bridges, and pools such buildings or structures on all can use.
