SHV rheological additive is a special processed montmorillonite clay thickener, the main material is magnesium aluminum silicate, its particle size is fine, it can be easily dispersed in the water-based system with conventional high-speed dispersion equipment.
Product features
Application area
■ Waterborne electrophoretic paint ■ Waterborne anticorrosive and antirust paint ■ Waterborne container paint
■ Waterborne wood paint ■ Coating or resin for casting ■ Water in water multicolor coatings
■ Sand in water waterborne architectural coatings ■ Other waterborne coating systems ■ Welding supplies
Main characteristics
■ In the resin and water-soluble system, the particle size is stable and repeatable after dispersion
■ To prevent the hard precipitation of pigments or fillers, organic and inorganic pigments can fully develop color
■ It disperses quickly in water
■ Special gel network structure enhances the performance of coatings.
■ Provides thermal stability of viscosity
■ Suitable for wide range of pH value (pH 5.0 ~ 11.0)
usage method
1. SHV is usually added in the grinding or beating stage, and then other dispersed phases (base material, pigment, etc.) are added. Only when SHV is fully hydrated can it give full play to its superior rheological properties. It is required to disperse SHV in water until it becomes colloidal (the dispersion time shall not be less than 15 minutes). Pre gel was prepared by
2.. The SHV can be dispersed in water at high speed and dispersed in water. A batch of precast gels will be prepared to be ready for production. The concentration of SHV pre gel can reach 5%. < br/> 3. SHV doesn't need the lowest activation temperature and is not sensitive to heat. With sufficient shearing and dispersion, SHV will form the best gel state. In order to disperse SHV with high concentration (5% ~ 10%) in water, 10% ~ 12% isopropanol can be added into the dispersion system, and then the base material can be added.
Addition amount
The addition amount of SHV is 0.3% ~ 1% of the total formula weight, which can be adjusted according to the suspension degree, rheological properties or viscosity requirements.
Operation and safety
The product has detailed information on operation and safety. Please refer to the relevant material safety data sheet (MSDS) before using the product.
Storage conditions
SHV stored in a high humidity environment will absorb moisture in the air, so it is recommended to store in a dry place.
packing
SHV can be packed in multi-layer cartons. Please contact the relevant personnel of Suzhou Guojian huitou new mineral materials Co., Ltd. to select the appropriate packaging form and weight.
term of validity
The shelf life of SHV is 12 months from the date of production.
