Description描述

THYOSIL E1549 is an acrylic emulsion polymer designed for manufacturing primers and topcoats for interior wood. It provides good early sandability after short drying.

是一款丙烯酸乳液聚合物，為家具或室內(nèi)木器底漆和面漆所設(shè)計(jì)。提供好的打磨性和快干性能。

Characteristics特性

Recommended as a sealer. It gives excellent clarity when is applied on both dark and light woods.

 具有清晰通透的質(zhì)感，可以適于明或暗的木材。

The excellent selfcrosslinking chemistry is responsible for its fast curing time, good stain and block resistance. 優(yōu)異的自交聯(lián)化學(xué)特性，支持快速固化，抗沾污抗龜裂。

Advantages優(yōu)勢(shì)

ü Excellent resistance to household chemicals優(yōu)異的抗家用（日用）化學(xué)腐蝕性

ü Very good adhesion非常好的附著力

ü Low water absorption 低吸水性

ü Highly sandability 高打磨性

Compatibility配伍性

THYOSIL E1549 is compatible with emulsions and resins manufactured by DIRANSA.

Application應(yīng)用

· A smooth surface is obtained by sand the wood with #150-320 grit sandpaper.

· 用# 150 - 320砂紙把木頭的表面打磨光滑。

· After applying a first coating, wait until it gets dried. Then sand the applied wood using #320 grit sandpaper.

· 油完第一層后，等到它變干。然后再使用# 320砂紙打磨。

· A second coat is applied and the wood is left for two weeks driying before performing the quality tests.

· 油完第二層后，放置2周后測(cè)試其品質(zhì)性能。

Formulation Tips 配方提示

?Coalescent（成膜助劑）: THYOSIL E1549 could be used at normal temperatures with the addition of coalescing solvents. The selection of an optimum coalescing system depends on the required drying rate, temperature and relative humidity. It is usually recommended 30% of coalescing solvents but it may be used lower levels depending on the porosity of the substrate, the type of application equipment, moisture conditions and co-solvents used in the formulation. Reducing the amount of coalescent allows faster drying but an excessive reduction may result in poorer film formation and consequently the loss of the stain resistance. Various types of coalescing may be used. It must be determined for each application. 
 It is recommended to allow the formulations equilibrating for at least 8 hours after addition of coalescing agents to obtain consistency results in the tests performed.

?Rheology Modifiers: 流變改性劑We suggest the use of associative thickeners. Keep in mind that the efficiency of urethane associative thickeners depends largely on the selection of coalescing adopted

我們推薦使用締合型增稠劑，記住聚氨酯締合增稠劑的效果取決于成膜助劑的選擇。

?Antifoam:消泡劑Antifoam should be tested in each case. Care must be taken with the concentration chosen as an excess of antifoaming can cause fish eyes defects or loss of transparency of the film.
