There are several epoxies used in commonly used with stone;
Megapoxy PM - uncured, this is a paste consistency, it has a 30-45 minute work time and a 24 hour full cure (at 25 degrees celcius). Available in white or grey. Megapoxy PF - a fast curing version of PM Megapoxy Megabond - a softer paste in its uncured form relative to PM Megapoxy 69 Gel - produces a fine glue line in mitre joins
Tenax is a polyester resin used for glueing and filling type repairs with stone and derivative products. The hardened product is shiny and polishable. There are several colours available to match to common Caesarstone, Quantum Quartz and Hanstone ranges of engineered stone.
Standard colours include Solido Paglierino (Beige), Bianco (White), Nero (Black), Transparente (Translucent) and Crystal (Clear).
Tenax also have a range of stone sealers, some of which are designed to enhance the existing colours within the stone.
Tenax comes in a 1 litre tin with a 45gm hardener.
We have a range of penetrating sealers designed to repel staining agents. We stock Lithofin, and Tenax sealers.
We stock a large range of sanitary silicone colours, including Batseal and Soudal. We also supply Maxisil A by special order.
Neutral Cure Silicone v Acetic Cure Silicone Neutral and Acetic refer to the two common curing systems of silicone. Neutral curing silicone releases methanol/alcohol as it cures. Acetic curing silicone releases acetic acid as it cures. Acetic curing silicone should not be used on metallic surfaces or alkaline surfaces such as concrete, plaster and brick.
Neutral cure silicones generally adhere better to a wider range of substrates. Acetic cure silicones tends to cure faster than neutral cure silicones.
Silicone and Painting We do not stock any paintable silicones. We do stock paintable sealants, however. Note that the success of painting a flexible sealant will in large part depend of the flexibility of the paint.
RTV Silicone RTV or Room Temperature Vulcanizing. The silicones available from Permatech all cure at room temperature.
High v Low Modulus Silicone This refers to the modulus of elasticity of the silicone. Low modulus show have better elongation properties relative to high modulus silicone. High modulus silicone tend to exhibit greater tensile strength and shore hardness (relative to lower modulus silicone).
Structural Silicone When a manufacturer describes a silicone as "Structural" or "Architectural" it is generally a reference to tensile strength relative to other silicones.
