Silopren® LSR 2750 TP 3824是一种用于注塑成型的双组分液体硅橡胶,它提供对各种基材(包括金属和工程塑料)的无底漆粘合,但不与模具粘合。在短时间后固化(例如100°C下1 h)或在室温下更长时间储存后达到完全粘合强度。这使得Silopren® LSR 2750 TP 3824成为在多组分注射成型或嵌件成型等集成工艺中经济高效地制造大量物品的最佳选择。主要特点和优点:底漆对许多基材的粘合力小,无需特殊的模具处理:最终粘合力随着时间的推移而增强,高温稳定性优异,在低温下稳定性和柔韧性优异,抗老化性能和耐候性好,介电和机械性能好,易半透明,易于着色。T色势应用Silopren® LSR 2750 TP 3824特别适用于零件制造,其中工程塑料和弹性材料需要在二次成型或共成型过程中结合,如密封件、汽车连接器、薄膜、减震元件等。零件由Silopren® LSR 2750 TP 3824制成。一般可用于无后固化的技术应用中,但不符合适用于制药或食品行业零件的法规。 Silopren LSR 2750 TP 3824 is a two-component liquid silicone rubber for injection moulding, which offers primer-less adhesion to a wide range of substrates including metals and engineering plastics, but without adhesion to the mould. Full bond strength is reached after a short post cure (e.g. 1 h at 100°C) or by longer storage at room temperature. This makes Silopren LSR 2750 TP 3824 the optimal choice for cost-efficient manufacturing of high numbers of articles in integrated processes such as multi-component injection moulding or insert-moulding. Key Features and Benefits Primer-less adhesion to many substrates No special mould treatment needed: Final adhesion builds up with time High temperature stability Excellent stability and flexibility at low temperatures Outstanding ageing behavior and weathering resistance Good dielectric and mechanical properties Easy pigmentable due to translucent colour Potential Applications Silopren LSR 2750 TP 3824 is particularly suitable for the manufacturing of parts, where engineering plastics and elastomeric materials need to be combined in an overmoulding or co-moulding process such as sealing elements, automotive connectors, membranes, vibration dampening elements, etc. Parts made from Silopren LSR 2750 TP 3824 can generally be used in technical applications without post-cure, but do not comply with regulations applicable for parts, which are intended for the pharmaceutical or food industry. |
