In daily life, when we buy adhesive products, the most common is PU foam adhesive and glass glue, most people actually can not tell what their specific differences are. In order for you to be able to distinguish their differences, the writers of SARZ take you through the details.

Let's first look at PU foam adhesive:

Foam adhesive is the product of the cross combination of aerosol technology and polyurethane foam technology. It is a special polyurethane product which is filled with polyurethane foam adhesive, catalyst and other components in pressure resistant aerosol tank. When the material is ejected from the aerosol tank, the foam polyurethane material will expand rapidly and solidify with the air or the moisture in the matrix in contact to form a foam.

The cured foam has a variety of effects such as caulking, bonding, sealing, heat insulation, sound absorption and so on. PU foam adhesive is an environmentally friendly, energy-saving and easy to use building material, which can be used for sealing and plugging, filling and sealing, fixing and bonding, heat preservation and sound insulation, especially for sealing and plugging and waterproof between plastic steel or aluminum alloy doors and windows and walls.

Application: PU foam adhesive can be applied to seal, insulate and fill wide joints, crevices and cracks. PU foam adhesive can be heat preservation, cold resistance, dry resistance, sound insulation and moisture proof. Things like gaps between partitions and ceilings, window frames, door frames, holes in walls, gaps between roofs and chimneys, seals around walls, ceilings, roof pipes, and holes and damage in walls.

PU foam adhesive can be used for bonding a variety of materials, such as metal, wood, stone, concrete and a variety of synthetic materials, such as polyester, polystyrene foam, PVC plastic, hard polyurethane foam.

Now let's talk about glass glue:

Glass glue is a commonly used adhesive at home, the main component is sodium silicate, soluble in water, sticky, also known as water glass, bubble alkali. Sodium silicate is a colorless, slightly colored transparent or translucent viscous liquid in the system with water as a dispersant. Solid sodium silicate is colorless, slightly colored transparent or translucent glass bulk.

The form is divided into liquid, solid, water quenching three kinds. In theory, such substances are called "colloid". Ordinary sodium silicate is a slightly light blue block or granular solid, after high temperature and high pressure dissolution is a slightly colored transparent or translucent viscous liquid.

There are many varieties of adhesives on the market, such as acid glass glue, neutral weather resistant glue, silicone neutral structural glue, silicone stone glue, neutral anti-mold glue, insulating glass glue, aluminum-plastic plate special glue, aquarium special glue, large glass special glue, bathroom anti-mold special glue, acid structural glue and so on.
