3x 2kg (6kg total) Epoxy Laminating Resin Kit Clear

This is for 3x 2kg kit. This is our Epoxy Laminating Resin (ELR 70) and slow hardener kit, giving excellent wet-out properties if you're laminating or skinning parts or maxing epoxy moulds. It has outstanding transparency and clarity (crystal clear) with outstanding adhesion, high strength and low shrinkage. We're very proud of this resin, and it is exclusively made in the UK for us. This resin is used a lot in marine, turbine and aerospace applications so it's super-reliable and predictable. It has a standard mix ratio of 100:30 (resin to hardener), a pot-life of 70-90 minutes and if you put it through a full cure cycle (slowly climbing to 70C) it has a glass transition temperature of 80C. We also include a free Sheer Mixing Stick, a laminated Technical Data Sheet, and a laminated Resin Mixing Ratio Chart. The Safety Data Sheet is available on our website. ApplicationAdd the Hardener to the resin, ideally in a polypropylene mixing bucket. Accuracy is crucial. Measure your resin and hardener by weight using electronic scales. You can combine HF70 and HS70 to tune the cure times but under no circumstances should thecombined weight of hardener break the 100:30 ratio. Cure times can be accelerated by choice ofhardener and cure temperature, but changing the ratio will result in (at best) a failed partial cure. Mix well with a shear mixing stick. Be sure to scrape the sides of your mixing bucket to haveeverything worked through. Minimum mixing time should be 2 minutes. For best results, post cure, in mould without releasing your part from the mould first. Thisassumes your mould and release agent is rated for the same thermal rating as your resin. For instance, our mould-making kit is safe to use up to 80° C, as is LR70. StorageThe resin and hardener described in this Technical Data Sheet have a usable minimum shelf life of 12 months provided they are stored between 10°C and 28°C, in a dry place, unopened and in their original containers. Over this time, the hardener may gradually slightly darken, but it is still perfectly usable. Over time, the resin may crystallise slightly, and the gentle application of a small amount of heat (on a batch by batch basis) will restore the resin to its original state. Ambient Cure and Pot LifePlease note that there are many factors involved in an ambient cure time, and we recommend testing until you have a cure process that suits your equipment, part, mould, layup, etc. As such, all our times listed herein are indicative only. Similarly, usable pot-life depends on many factors. A major factor is increasing bulk which results in an increased exothermic temperature rise caused by the reaction between resin and hardener. Avoid keeping a large quantity of the mixture standing in one compact mass - e.g., in a mixing beaker or similar "bulk container". Post (accelerated) Cure Time: GuidelinesPost curing at elevated temperature is always advisable for room temperature curing resins to stabilize the component and to achieve the best possible mechanical properties from the resin. An elevated temperature post-cure is required for parts that will be subjected to higher temperatures during operation. Users should evaluate the best conditions of curing or post-curing depending on the component size and shape. For best results, conduct the post cure in the mould without prior release (first ensure that the mould and release agent are compatible with the post cure temperature). Please note that ovens vary for their ramp time. Your ramp time should never be faster than 1°C/minute. You should always cure your part at a higher final temperature than the Glass Transition Temperature (TG) your part will be operating at. We offer two cure profiles per hardener – Intermediate performance (which is sufficient for a lot of scenarios) and Maximum performance, which is the maximum available for that resin/hardener combination. Please note that the maximum temperature we recommend is 80°C . Handling Precautions Please see the safety data sheet for LR70 for specific instructions when handling this resin and hardener. HS70 and HF70 Hardener: This material iscorrosive. You must avoid contact with the skin and eyes. If contact with eyes does occur, the eyelids - held open - should be thoroughly flushed with water, and medical attention should be sought immediately. If skin or clothing comes in contact with the hardener, the affected skin area should be thoroughly washed with soap and warm water, and the contaminated clothing removed and washed before re-use.
