三、 the application β>'of the proposed In the original non-transparent< high-grade powder coat, th∞×∑¥e amount of transparencφ£×☆y should not add too much flou↓₽§r, Chatham appropriate amount☆•φ of 3-8%. At some special add-ching at"₹ the end of talcum poπ>Ωwder, crystal, and all at the end o≈±f high-solids primer fo§±r no additional cost, shoulβ••φd be cut some talcum po↓€'wder, then add (subtract some ®∞amount of talc) 1.5-2 t ≤imes the transparent powder. But the po₩<wder should not be more th¶ <an 40% of the total. Powder added to a transpa•₹≠rent coat as a result of an increas' e of film hardness an•αd toughness, grinding may be affect♥¥↔ed slightly. The same period last year talc, transp<₽arent powder in the paint after thi€♦nning more precipitation, so prev←<←ention measures should ₩πbe appropriate to strengthen Shen. Production is expected$₽' to vote yes, in the course of mixer oλperation, transparent powder∞¥ into a small amount should b'♠e slow, otherwise it wil₩ l affect their dispersi×↔↑>on 四、the role and performance Transparent powder used in' >Ω paint, the paint can increase® the hardness and toughness, ★¥™and scratch resistant≥≥® finish enhance the capa↕≈city of the glass can be expensive to ≤♥₽replace; Transparent powder paλ✔✘int to enhance the effect÷ of extinction can be an alter®σ✘φnative matte powder, mat$←te finish to reduce the amount★$ of powder; Product transparent powder good decay r∑¥esistance, used in paint, the φ σ←products can enhance π weather resistance; Transparent powder us∞≠ed for filling in at ←' >GLAZE, transparency, low absorpti♦∞←✘on, the concept can feel better★↔.
