MAS Epoxies Slow Hardener

MAS Slow hardener is formulated for use with MAS epoxy resins and can be applied in a wide range of conditions where increased working time is required.

We highly recommend MAS Slow Hardener when coating or laminating large surfaces. The Slow formulation cures blush free and eliminates the need for time consuming wash downs during on-going laminations or repetitive build coats.

Use this hardener (200-250 poise) with MAS low viscosity epoxy resin for fast wet-out of reinforcing fabrics.

Note: Due to this item's high hazardous content, the 4 gallon and larger containers cannot be shipped by UPS or FedEx under any circumstances.

    Great product

    Not as toxic as other hardeners. 2:1 mix with Mas resin as opposed to 5:1 West Systems. No yellow tint as with West System

    nice and slow

    it works nice and slow giving you a lot of working time. In colder temps it might be better to use a faster hardener but I have not tried it.

    I first used this product while building Skerry from Chesapeake Light Craft. It's supplied with the kit. It's long working time make it very easy to use for the novice boat builder. The beautiful amber hue it imparts to wood and it's diamond hard finish will give you a boat that will be passed down for generations. Make sure to cover with a Good UV varnish so the epoxy doesn't yellow with age.

    I work with reclaimed wood this combined with the low viscosity resin does a great job of filling cracks and securing knots, saves me a lot of time.

    The Mas slow hardner system is an excellent choice for people who need a little extra set up time as it is slower to go off than some other epoxies I have used. It sets up clear on it's own and mixes well with additives. I will be using this product on all my new projects.

    a perfect blend

    I used the MAS Epoxy resin products for repairs on an Hydra Sports Aero Cobra I am restoring. The slow hardener was a great choice for the repairs I had and did everything MAS said it would. Its slower set up time gave me plenty of time to work. It was easy to mix and apply. I ran out with one small job to do so I bought another brand locally. I greatly preferred the MAS over the other brand.
