As a dispersion in water (usually an emulsion), PVAc preparations are used as adhesives for porous materials, particularly for wood, paper, and cloth, and as a consolidant for porous building stone, in particular sandstone. [5] PVAc is considered a food-safe material, [6] and is thus used often in such applications (e.g., in food packaging ...
Polyvinyl alcohol (PVOH, PVA, or PVAl) is a water-soluble synthetic polymer.It has the idealized formula [CH 2 CH(OH)] n.It is used in papermaking, textile warp sizing, as a thickener and emulsion stabilizer in polyvinyl acetate (PVAc) adhesive formulations, in a variety of coatings, and 3D printing.

The material has good clarity and gloss, low-temperature toughness, stress-crack resistance, hot-melt adhesive waterproof properties, and resistance to UV radiation. EVA has a distinctive vinegar-like odor and is competitive with rubber and vinyl polymer products in many electrical applications.
Wood glue is an adhesive used to tightly bond pieces of wood together. Many substances have been used as glues. Traditionally animal proteins like casein from milk or collagen from animal hides and bones were boiled down to make early glues.
Epoxy crack injections are typically used for structural purposes while hydrophobic or hydrophilic polyurethane injections are used to seal cracks to prevent penetration of moisture or water. Concrete is both strong and inexpensive, making it an ideal product in construction. However, concrete is not waterproof.
Fevicol is marketed as a white adhesive, described in company literature as a poly-synthetic resin.It is manufactured through the synthesis of formaldehyde and urea. [4]The product line includes various formulations designed for specific attributes such as bonding strength, impact resistance, curing time, sag resistance, shrinkage, versatility, fire resistance, shock and vibration resistance ...
