Home improvement environmental glue choice

Glass glue: in the home improvement is necessary to use, we can go to building materials supermarket to buy some high-end products, will not cause too much pollution. Glass glue should be used for adhesive UV highest decoration, we need to use it in a lot of places, but most of the owners are not allowed to buy, but to use their own installation work, and this is often to buy hidden inferior glass glue not only taste, and it will become mildewed, fracture and fall off.
Acid glass glue: use when there is a very exciting smell, the sticky force is relatively strong, and some of the material is corrosive, buy the time to be careful, if not necessary, do not buy. Glass glue and white, transparent, black and other different colors, according to my experience, general transparent glass glue can be used in most places, home ready to choose this color.
The white latex: Decoration usually requires the use of white latex in carpentry, currently on the market some new green white latex, the formaldehyde and benzene release can be controlled to the lower range, as long as the purchase of the white latex, in the home can be used in moderation. Ceramic tile adhesive UV: do not use the home, the glue used only in some exhibition hall decoration, pollution is relatively large.
The 309: also known as glue adhesive, almost no use, if workers put to use this glue, can see if there are other methods without the glue.
Stone adhesive: people who usually install natural stone can use it, basically can not be avoided.
The rubber floor: when installing flooring, may use, but as long as the lock floor floor structure design is reasonable, the quality of clearance, do not need to use glue in the installation, so when the purchase floor should also pay attention to the installation need glue.
The wallpaper glue: must use wallpaper, should choose a special water wallpaper powder, mixed with water, many are made from plants such as potato rhizome extract, less pollution.

According to the application of commonly used glue classification

1, apply coating:
Acrylic acid type: easy to use, more than ten minutes to dry at room temperature. With good electrical and physical properties, fungal resistance. Low heat release or no heat release during curing can protect against heat sensitive components. Easy repair.
Polyurethane: it has good moisture resistance, chemical resistance, very good electrical properties. Most single component polyurethane coatings require careful application and strict control over coatings and curing environments. Polyurethane coating has weldability, can use electric iron to remove component, repair is easier.
Silicone: it has the highest flexibility, high moisture resistance and fungal resistance. It has the properties of chemical resistance and easy repair. It has excellent electrical performance and good thermal performance. Solvent free silicone coatings can be heat cured or moisture cured. UV curing type: most of these chemical types can be UV cured. Solvent-free products can be cured in UV light / visible light within a few seconds. In addition to acrylic, polyurethane, and silicone based UV cured Conformal Coating, there are epoxy and acrylic modified polyurethane UV cured Conformal Coating. Encapsulation:
Epoxy resin: one component or two component, good adhesion to most substrates, chemical resistance. With very good electrical properties, curing is virtually without release of volatiles.
Silica gel: one component or two component, can be 100% solid, very friendly to the user. It has high purity, low toxicity and excellent weather resistance. The operating temperature to 600oF in 100 (-37 – 135oC). Can have the best product thermal cycling performance.
Polyurethane: one component or two component products, good adhesion to most materials, and wear resistance. Good electrical properties with high anti drop strength. Very good low temperature flexibility, the highest operating temperature of 250oF (121oC). UV curing type: one component or two component, 100% solid. Exposed to UV or visible light, solidify within 10-20 seconds. Fast curing and improved efficiency.
2, seal:
Acrylic: acrylic sealants are good for most surfaces and are still plastic in exposure to UV light or other environments. The utility model is universal and is used in many outdoor facilities. After curing, it can be coated.
Polysulfide type: one component or two component, 100% solid. Very durable, mainly used in aerospace and industrial window seals. Polysulfide products are resistant to all smoke.
Polyurethane: polyurethane sealant is mostly a single component, good adhesion and extensibility. It is a non corrosive and flexible product that can bind many substrates and still have good performance over a wide range of temperatures and is resistant to most chemical and climatic conditions.
That is a kind of multifunctional silicone sealant, with the wide operating temperature range (76oF to 600oF). A single component of silica gel solidifies to form a tough solid. Is a very good universal sealant, with good weather resistance, wear resistance, moisture resistance and ozone resistance. Silicone sealant is generally easy to extrusion molding, easy to handle.
