  • SWD1006 low density spray polyurethane foam US-made wood structure buildings heat & sound insulation materials

    SWD1006 low density spray polyurethane foam US-made wood structure buildings heat & sound insulation materials

    Timber structure buildings are very popular in the Europe and America that almost occupied 90% of residential house (Single house or Villa). According to the global market statistics in 2011, the buildings made by North American wood and its matching materials took 70% of global wood structure buildings market share. Before 1980s, rock wool and glass wool was chosen to insulate American wood structure buildings, but then they were found having many Carcinogen bad to human’s health and with inefficient insulation performance. In the 1990s, the American Wood Structure Association proposed that all the wood structure buildings shall apply low density polyurethane foam for heat insulation. It has excellent heat and sound insulation performance, safe and Eco friendly. SWD low density polyurethane spray foam developed by SWD Urethane., USA applied with full-water foaming method, it will not destroy the ozonosphere, environmentally friendly, energy efficient, good insulation effect and price competitive. It has become a priority product for wood structure villa insulation in the American market.

Applied with direct spray technology, no seams among foam layers that a complete impermeable layer is formed on the substrate. It creates a protection layer avoiding water absorption and perfectly resolves the building walls water-leaking problems and heat insulation issues. 

  • SWD969 Metallic anticorrosion coatings

    SWD969 Metallic anticorrosion coatings

    SWD969 is composed of high-performance anti-corrosion resin as film-forming base, it added bright metallic flakes materials. Its film-forming resin contains a large number of ether bonds, urea bonds, biuret bonds, urethane bonds and hydrogen bonds, which makes the film-forming coating dense and tough, with excellent mechanical and physical properties and anti-corrosion properties. After pretreatment, the metal flakes material can be evenly and orderly arranged during film formation. Due to its outstanding length diameter ratio and strong anti-corrosion ability, it will greatly prolong the penetration and damage of corrosive medium during application, so that the coating can play the role of thick film coating acted under thin conditions. The selected metallic materials are bright flakes, which can effectively reflect light and heat radiation, achieve the effect of cooling and energy saving, make the building environment more comfortable, and the stored materials more stable. The metal flakes in the coating are overlapped from bottom to top, so that the coating has a conductive effect, which can prevent electrostatic accumulation and make the production area safe.
