Little knowledge about white latex adhesive:
White latex adhesive is a highly utilized adhesive with a wide range of uses, large volume, and long history. It is an adhesive with a broad scope of application, large consumption, and a long-standing history. Today, let's learn some little knowledge about white latex adhesive.
1. What is white latex adhesive and what can it do?
Under the action of an initiator, it is polymerized from vinyl acetate monomer into a thermoplastic adhesive. It has good adhesion to panels, solid wood, and wooden flooring, with high bonding strength, colorless and transparent, and good toughness.
2. How to identify the quality of white latex adhesive.
In terms of quality, when we choose white latex adhesive, high-quality latex has a uniform thickness, while inferior latex has delamination and sedimentation. Stirring the white latex adhesive with a brush, high-quality white latex adhesive can form a long, thin, uniform strand, while inferior white latex adhesive cannot form such a strand.
In terms of smell, high-quality white latex adhesive has no strange smell, only a faint fragrance. Inferior white latex adhesive has a pungent smell, or some fragrance may be added to cover the smell, making it sweet but still pungent. The higher the solid content of white latex adhesive, the stronger its bonding strength. For general household use, 30%-35% solid content is sufficient. After hand rubbing, high-quality white latex adhesive has a good texture, is smooth, and does not easily come off.
3. Is white latex adhesive toxic?
White latex adhesive is a water-based adhesive. Compared with other adhesives such as solvents, it is an environmentally friendly product. No toxicity has been found so far. However, prolonged exposure can irritate the skin and eyes. If accidentally contacted with skin and eyes, rinse with plenty of water. If swallowed, seek medical attention immediately. In fact, whether white latex adhesive is toxic depends largely on the product itself.
Due to differences in corporate standards, management, technology, etc., the quality of white latex adhesive on the market varies. Some manufacturers add different additives to improve the performance of white latex adhesive, such as benzene, formaldehyde, and toluene, which are harmful to the human body. If the content of harmful substances exceeds the limit standards, it is definitely toxic.
Formaldehyde in white latex adhesive products mainly comes from synthesis, residual free formaldehyde, or incomplete reaction, or is added to the adhesive as an auxiliary agent, adhesive, or preservative, causing excessive formaldehyde. If free formaldehyde exceeds the national mandatory standard value of 1.0g/kg, it indicates that the formaldehyde exceeds the limit.
The above has introduced the relevant little knowledge about white latex adhesive in detail. I hope the above content is helpful to everyone.
