What are the main components of paint?
Coating is generally viscous liquid or powder material,form a continuous film after coating on the surface of protection,decoration and special function(fire,rust,insulation,etc.)of materials,the early called paint by vegetable oil as the main raw material,were gradually replaced by synthetic resin coating and said,now coatings including emulsioni paint,water-based paint,oil paint,etc.
The main ingredients of paint
Film materials,pigments,solvents,fillers,additives
Film forming matter
The basis of the coating,also known as the fixing agent,determine the main factors of film performance,including oil(drying oil,semidrying oil,non-drying oil),natural resin,synthetic resin,alkyd resin,acrylic resin,chlorinated rubber,resin,epoxy resin,etc.).
pigment
Is mainly used for colored coatings(paint),decorative and protective effect,the commonly used with titanium dioxide pigment(sharp titanium,ruby),lithopone,zinc oxide,iron oxide red,zinc chrome yellow,yellow and other inorganic pigment and azo,diketone pyrrole,phthalein ketoneses oxazine,ketone,etc organic pigments.
solvent
Including true solvents,cosolvent,diluent,film-forming substances used to dissolve and disperse coatings,and there is water,toluene,xylene,gasoline,kerosene,mineral oils,alcohols,esters,etc.
packing
Extender pigment,there is no cover and tinting strength white or colorless powder,calcium carbonate,kaolin,talcum powder,barium sulfate,aluminum silicate,silica,etc.
additives
Additives such as drier,plasticizer,thickening agent,dispersant,anti-deposition agent and anti-hair spray are used to modify certain properties of coating.
Coating materials commonly used inorganic filler has the following kinds:heavy calcium carbonate,light calcium carbonate,talc,wollastonite,kaolin,barite,mica powder.
For packing products,particle size distribution of the fillers have very strict requirements,a common method in the mills is used for packing powder particle size laser granulometer detection.
Our company is a professional manufacturer of barium sulfate,the powder coating on the market in the process of production,all you need to add a certain proportion of barium sulfate,the dispersion effect is good,good weather resistance,surface glossiness higher several advantages.
