Waterborne products

Today, the civil engineering and coatings industries are without any doubt convinced of the advantages of using waterborne epoxy systems: these systems are environment‑friendly, they offer enhanced work comfort (less smell) and reduced toxicity for the applicators working in closed areas. They are not flammable, they allow for easy cleaning of the application tools with water. These systems also do exhibit excellent adhesion on concrete and on humid surfaces, and they can even be used on wet concrete.

However, formulators are still reluctant to switch to waterborne epoxy binders because they still encounter problems using those:

waterborne systems tend to cure slowly; their application thickness is often limited; the final gloss of cured coatings is also known to be poor, because of an imperfect film formation process. Finally, the protective efficiency of aqueous epoxy formulations, in particular on metal, is regularly questioned and does not always attain the performances achieved by their non-aqueous counterparts.

In QR-Polymers, we believe we can offer waterborne curing agents which address these concerns. Through R&D and close cooperation with our customers, we are continuously improving and expanding our product range to meet today and tomorrow market requirements.

A summary of our main waterborne products can be found below.

Waterborne zinc rich primers

Waterborne zinc rich primers

There is increasing interest globally for water-based industrial paints. Water-based zinc rich primers are difficult to prepare due to the reactivity of zinc powder with water, evolving hydrogen gas. As a result, solvent-based materials are still widely used. QR Polymers has developed an innovative concept of a water-free water-based hardener: RD-0205WH which has been specifically developed for this application. The zinc is dispersed in the hardener which contains no water and is mixed with the water-based resin component containing other fillers and additives with additional water to the desired solids content before application. Dispersions of zinc powder in RD-0205WH are stable to settling and do not produce gas on prolonged storage even at elevated temperatures.

RD-0205WH is an isolated amine adduct supplied as 70% solids in propylene glycol n-butyl ether. RD-0205WH is miscible with water and is designed for use with modified or non-modified standard liquid epoxy as well as with liquid resin emulsions and solid resin dispersions (such as E‑Pos 1011W55). RD-0205WH has an easy 1:1 recommended mix ratio with standard liquid epoxy resin (EEW 190 g/eq).

An additional benefit of RD-0205WH is its inherent pseudoplastic nature, increasing the stability and resistance to settling of zinc rich paints with the zinc dispersed into RD‑0205WH without water. Water and the resin component are added immediately prior to application.

RD-0205WH exhibits high reactivity at ambient temperature and forms excellent films when cured with solid or liquid epoxy resins.

RD-0205WH requires no ADR labelling.

水性环氧固化剂系列

水性环氧固化剂系列

毫无疑问当今水性环氧体系在土木工程和涂料领域的应用具有明显的优势。水性体系它环保,它提供工作的舒适度(如低气味)以及减少封闭环境下对操作者的毒性危害。它们不易燃,它们用水即可轻松清洗操作设备。 水性体系在混凝土和潮湿表面表现出良好的粘接性,另外它们也能用于湿润的混凝土。

然而,操作者不愿意做“油转水”的切换是因为他们会碰到诸多问题,如:水性系统通常固化比较慢;它们应用的膜厚通常有限;固化后涂料由于不完全的成膜过程通常光泽较差;最后水性环氧体系的防腐效果,特别是在金属上的防腐效果常常被质疑,通常无法达到溶剂型体系的防腐效果。

 

可是在日益严峻的环境保护压力下,国家近年出台多个环保政策禁止溶剂型涂料的使用。

  • 2015年2月1日国家对VOC含量超过420克/升(含)的涂料征收4%消费税政策。
  • 国务院办公厅发布《贯彻实施质量发展纲要2016年行动计划》,明确提出开展含挥发性有机物涂料质量标准提升行动。
  • 2016年3月2日国家发改委和商务部正式发布《市场准入负面清单草案(试点版)》,涉及多个涂料板块被禁限的产品项目。

 

在禁止溶剂型涂料使用的同时,国家今年密集出台各类政策鼓励和推广应用水性环保涂料:

  • 2016年4月26日,发改委、工信部等24部门联合印发《关于促进消费带动转型升级的行动方案》,提出推广使用水性涂料等环保装修材料;
  • 2016年5月18日,国务院办公厅发布《关于促进建材工业稳增长调结构增效益的指导意见》,指出要加快推广应用水性涂料产品;
  • 2016年10月11日,工信部发布《建材工业发展规划(2016-2020年)》,提出推广应用水性、粉末和高固体分等低挥发性有机物(VOCs)的涂料,发展无污染、健康环保的装饰装修材料;
  • 2016年10月14日,工信部发布《石化和化学工业发展规划(2016-2020年)》,提出加强环保型涂料产品的研发和推广应用,综合整治挥发性有机物(VOCs);
  • 2016年11月13日,工业和信息化部正式发布《国家鼓励的有毒有害原料(产品)替代品目录(2016年版)》《目录》,涉及大量的水性涂料替代溶剂型涂料产品项目。

 

面对水性环氧体系在中国市场的广阔应用前景,荷兰QR-Polymers公司相信,我们提供的水性环氧固化剂能满足市场的要求。通过研发和与客户的深入合作,我们不断提升产品品质和扩充产品品类以满足日前及未来市场的需求。让我们携手共筑美好未来。
