Foam caulkCommonly known as foaming agent,full name is single-componentpolyurethane foam caulking agent, which is a must in the door and window industry. Indispensable auxiliary products, in the past, most of the gaps in doors and windowswere filledCement mortar, rock wool and the like are filled. Until 1994, the German foam caulking brand “Weigu” entered the Chinese market , Foam caulking has entered everyone’s field of vision andhas made great contributions to the door and window industry.
As building insulation materials for doors, windows and curtain walls, traditionalbuilding materialsmaterials, Waterproof but not thermal insulation, thermal insulation is not waterproof, and the emergence of foam caulk breaks this barrier. It is a common problem that once the waterproof layer leaks, the insulation layer will lose its insulation function, Compared with other building insulation materials for doors, windows and curtain walls, foam caulkinghas obvious advantages: span>
Foam caulking agenthas the function of one material with multiple uses, and has the functions of thermal insulation, waterproofing and sound insulation at the same time , vibration absorption and many other functions.
1. It has stable chemical properties, long service life, and does not pollute the surrounding environment;; font>It self-extinguishes when removed from the fire, and only chars without dripping when burning. The size and shape of the charring layer remain basically unchanged. It can effectively cut off the entry of air, prevent the spread of fire, and has good fire safety performance.
2. Strong bonding performance (requires no intermediate bonding material), firmly bonded to roofs and exterior walls, good wind pressure resistance; can be made font>Overall spraying construction, flexible gradient technology can effectively prevent the waterproof layer from cracking;mechanized operation , automatic batching, uniform quality, fast construction and short cycle.
3. Excellent thermal insulation performance, with the lowest thermal conductivity of all domestic building materials(≤0.024), the thermal insulation material with the highest thermal resistance, the thermal conductivity is only EPSfoamhalf of polystyrene board.
4. Foam caulking agentcontinuously dense skin and close to 100% high-strength interconnected wall closed cells, withveryideal water impermeability. The spraying method is used to construct the waterproof and thermal insulation layer continuously and seamlessly, forming a seamless roof and an integral exterior wall thermal insulation shell with excellent waterproof and impermeability performance.
As a new widely used thermal insulation and waterproof integrated new building material, foam The application of caulking agentinsulation materials in the domestic construction industry is still in its initial stage. Fortunately, in order to speed up the innovation of building insulation materials and promote the promotion and application of foam caulking agents in the field of building energy conservation, construction The Ministry has specially established the “Polyurethane Building Energy Saving Application Promotion Working Group“, To promote foam caulking thermal insulation and waterproof materials in the domestic building energy-saving industry Applications.
Foam caulking agentcan make the gaps in doors and windows very good ���Charging quickly makes the bubbleexpand70-80 times,Recommended foam caulkbefore use , Sprinkle some water on the surface of the window sill or sprinkle some water on the surface after applying foam caulk. This dries fasterand has better cell density
Foam caulking agent is a special sealing thermal insulation and waterproof material, consisting of The composition is also very complex. It is generally best not to touch it on clothes, otherwise it will be difficult to clean. It is used in decorating the entrance, installing security doors, sealing balconies or installing plastic steel doors and windows, and broken bridge aluminum doors and windows.Foam Caulkingproducts.
