High performance epoxy toughening modifier

RF-400

产品概述RF-400既是环氧树脂高性能增韧改性剂，又是良好的活性稀释剂。 Product Overview RF-400 is both a high-performance epoxy toughening agent, and is a good reactive diluent. 具有很好的增韧性能和反应活性，可大幅度地提高环氧树脂固化物的耐冲击、耐压缩、抗开裂以及黏结强度等物理机械性能。 With good toughness properties and reactivity, can greatly improve the impact resistance of cured epoxy resin, resistance to compression, anti-cracking and bond strength and other physical mechanical properties. RF-400与各类环氧树脂、环氧固化剂及助剂都有极好的相溶性；对硅微粉、氧化铝等各种无机填料和颜料具有浸润性；添加于环氧树脂固化体系中，可显著延长其可使时间（延长约1/3）和降低固化放热峰值，使环氧树脂固化反应平稳。 RF-400 and various types of epoxy resin, epoxy curing agents and additives have excellent compatibility; of silica, alumina and other inorganic fillers and pigments with invasive; added to epoxy resin system , can significantly prolong the time (to extend about 1 / 3) and lower curing exothermic peak, so that a smooth epoxy curing reaction.
应用领域各类环氧胶粘剂、结构胶、环氧涂料、环氧地坪、环氧玻璃钢/复合材料以及环氧电工、电子浇注、灌封料、光缆绝缘体等。 Various types of epoxy adhesives applications, structural adhesive, epoxy coating, epoxy floor, epoxy glass fiber / epoxy composite materials, and electrical and electronic casting, potting material, cable insulation and so on.

使用方法及建议用量 Use and recommended dosage
1.结构用胶粘剂参考用量为环氧树脂质量分数的10～20%。 1. Structural epoxy adhesive mass reference amount of 10 to 20%.
2.其他环氧体系，如胶粘剂、涂料等体系改性；参考用量为环氧树脂质量分数的20～100%。 2. Other epoxy systems, such as adhesives, coatings and other system modification; reference to the amount of epoxy resin content of 20 to 100%.
3.固化剂的用量按环氧树脂的质量分数计算，在CYH-277的用量较大时，固化剂的用量应酌情减少。 3. Epoxy resin curing agent according to the mass fraction of the amount of calculation, the amount of the CYH-277 is larger, the amount of curing agent should be reduced as appropriate.
4.经RF-400改性的环氧体系，如果其粘度不符合用户产品要求； 5.为避免在混合工艺上产生气泡，建议最后一道工序添加RF-400，并采用低速（60～80转速/分）机械搅拌或三辊碾磨机生产。 4. The RF-400 modified epoxy system, if the viscosity does not meet the requirements of consumer products; 5. In order to avoid bubbles in the mixing process on the proposed final steps to add RF-400, and using low-speed (60 ~ 80 rpm / min) mechanical agitation or three-roll mill production.
性能特点 Features
1、可大幅度提高固化物冲击韧性和黏结强度（在环氧体系中添加环氧树脂质量分数的20% 时，冲击韧性＞23 kJ/m2，剪切强度＞18 MPa）。 1, can greatly improve the toughness of cured and bond strength (in the epoxy system, add 20% mass fraction of epoxy resin, the impact toughness of> 23 kJ/m2, shear strength> 18 MPa).
2、物理机械性能优良和综合特性优异。 2, the physical and mechanical properties of excellent quality and comprehensive features. 固化物试件经腾水连续沸煮7昼夜（168h），粘结剪切强度无下降；经2160小时加速湿热老化后，拉剪强度不下 Teng specimens cured by boiling water 7 consecutive days and nights (168h), no decline in bond shear strength; after 2160 hours accelerated heat aging, the tensile-shear strength less than

降；符合国家《混凝土结构加固设计规范（GB50367—2006）》的标准要求。 Down; line with the national "reinforced concrete structure design (GB50367-2006)" the standards.
3、工艺性能优良。 3, process and excellent performance. 经RF-400改性的环氧树脂或固化剂产物，可长期存放，不分层、不析出；可完全解决环氧树脂冬季结晶问题。 The RF-400 modified epoxy resin or curing agent product of long-term storage, not hierarchical, no precipitation; winter crystalline epoxy resin can be completely solved the problem.
4、RF-400可完全参与环氧树脂的固化反应，成为环氧树脂固化物交联网络结构的部分；从而替代部分环氧树脂基料，有效地降低环氧体系成本。 4, RF-400 can be fully involved in the curing reaction of epoxy resin, a cured epoxy resin cross-linked network structure of the part; to replace part of the epoxy resin material, effectively reducing the cost of epoxy.
