水性烤漆用丙烯酸聚合物THYOSIL IM76

Thermosetting  acrylic polymer  热固性丙烯酸聚合物

Description描述

THYOSIL IM76 is a DMEA (Dimethyilaminoethanol) neutralized resin solution.

THYOSIL IM76是DMEA（二甲基乙醇胺）中和的树脂溶液。

THYOSIL IM76 was specially developed for producing high resistance waterborne industrial enamels when it is formulated with monomeric melamine resins.

 THYOSIL IM76   专为与氨基树脂配方用于生产高抗水性工业搪瓷和瓷漆而开发的。

THYOSIL IM76 plus Melanine resin leads to industrial baking enamels that feature outstanding spray characteristics and film properties.

THYOSIL IM76加氨基树脂 做出的工业烤漆具有优异的喷涂特性和成膜性。

Application 应用

Enamels based on THYOSIL IM76 solutions may be easily sprayed. They atomize finely and without sagging.

The enamels formulated on base of THYOSIL IM76, show similar properties to those obtained with solvent-borne systems and match or surpass those of other water reducible coatings made with high levels of co-solvents.

Additionally, enamels made with THYOSIL IM76 solutions, exhibit less sensitivity to variations in the environment conditions (temperature/relative humidity).

由IM76 做出的瓷漆有优异的喷涂性，雾化精细，不会流挂。与溶剂型产品相比显示出相似或优于它们的特性，同时所用助溶剂含量低。此外用IM76配置的瓷漆，对环境要求不苛刻（温度/相对湿度）。

Application Test 应用测试

1.       Moisture content of wood should be less than 2%. The wood was dried in a oven at 212°F.

      木材水分应当低于 2% ，木材应当在100’C的烘箱中干燥。

2.       Once the MDF is fully dried, apply 1 layer by spray. 板材干燥后喷涂一遍

3.       It is dried in oven for 5 minutes at 122 ° F. 在50’C的烘箱中干燥5分钟

4.       Finally, it is cured for 30 minutes at 300 ° F.最后再在150’C的烘箱里固化30分钟

5.       A minimum of two layers is suggested. 建议至少涂2遍。

Chemical resistance 耐化学性

Formulation Tips 配方提示

Enamels based on THYOSIL IM76/melamine blends offer a unique stability advantage, even when catalyzed, over aqueous alkyd/melamine systems. Care should be taken just to select with monomeric melamines. Polymeric types that were evaluated gave hard, brittle films with poor resistance properties.

由IM76与氨基树脂经过催化反应做出的瓷漆，比醇酸树脂/氨基树脂对比 ，具有独特的稳定性的优势。在此推荐单体型氨基树脂，聚合类型的效果不好--成膜较脆，抵抗力差的属性。

可接受的氨基树脂如：RESIMENE745（孟山都），Cymel 301, and Cymel 303（美国氰特公司）

Enamels made with THYOSIL IM76 do not require external thickeners for viscosity control. Upward viscosity adjustments can be made easily and with quick equilibration by adding a dilute solution of DMAE. They should be adjusted to a desired viscosity rather than to a given pH, because very small changes in pH can mean substantial changes in viscosity.

用IM76制成的瓷漆不需要另外添加增稠剂来调节粘度，向上调粘度时可以添加二甲基乙醇胺（DMEA）的稀释液。可以调到所需要的粘度，而不是给定的PH值。

» Coalescent: Even at low levels of co-solvent, THYOSIL IM76 provides excellent substrate wetting without foam while adequately meeting antipollution requirements.

The co-solvents contained in the suggested formulations are n-butanol and 2-butoxyethanol and dipropylene glycol, although other exempt solvents are also compatible.

成膜助剂：即使在助溶剂低添加的情况下，IM76在基材上表现出优异的润湿性和避免泡沫的产生，同时满足了防污染的要求。

» Defoamer: The use of n-butanol provides adequate defoaming. Formulators are encouraged to test other commercial defoamers for alternate choices.

消泡剂 ： 使用正丁醇提供了足够的消泡的作用。客户在应用配方时也可以选择测试其他市售消泡剂来代替。

» Catalyst: p-Toluenesulfonic acid (pTSA) catalyzes the crosslinking reaction between THYOSIL IM76 polymer and the monomeric melamine resin. When added to the formulation at a level of 0.2 percent on binder solids, pTSA promotes complete cure in a 30-minute bake at 300°F.

Faster bake schedules suggested for complete cure are 15 minutes at 325°F, 10 minutes at 350°F, and 5 minutes at 375°F.

pTSA is added to the formulation as a solution in water after it is combined with equal parts of DMAE. The addition of pTSA as a DMAE salt overcomes a common problem in water-borne enamels. It prevents the flocculation and kickout that can occur if the catalyst is added in the acid form. It also lends exceptional stability to the wet formulation.

催化剂 ：对甲苯磺酸（PTSA）催化Thyon IM76聚合物与单体氨基树脂之间的交联反应 。当加入粘合剂固含量的0.2%的水平PTSA推动固化温度为 150`C时间为30分钟 ；加快固化时间建议160`C时间为15分钟； 180`C时间为10分钟  ,  190`C时间为5分钟 。

在水中将PTSA溶解后加入等量的DMEA。加入的PTSA与DMEA的中和适合于水性瓷漆的体系。这样可以防止催化剂以酸的形式加入导致絮凝和回位，它在水性体系里是稳定的。
