What is the curing agent in sylgard 184?
Dow SYLGARD™ 184 Clear is a two component, flowable, room temperature and heat cure silicone curing agent with good dielectric properties and flame resistance.
What is sylgard?
SYLGARD®184 is a silicone based elastomeric kit that is a two component system with a polymeric base and a curing agent which cross-links with the polymeric matrix. The resulting composite formed is a polydimethylsiloxane (PDMS) with tensile strength (UTS) of ~5.2 MPa and shore hardness of ~44 at room temperature.
What is PDMS curing agent?
Polydimethylsiloxane (PDMS) is a two-part polymer (Base Elastomer and Curing Agent). Our lab uses Sylgard 184 from Dow Corning. The standard mixing ratio for PDMS is 10-parts base elastomer and 1-part curing agent. This ratio provides the mechanical properties that are desirable and optimum biocompatibility.
How do you clean sylgard?
Sylgard is very difficult to clean up. It will not dissolve with soap and water. Work over disposable bench paper and wipe up any spills with paper towels. Mixed Sylgard may be allowed to cure so it can be peeled from lab surfaces.
How do you mix Sylgard 184?
Thoroughly mix SYLGARD 184 silicone elastomer, base & curing agent, in a ratio of 10 parts base to 1 part curing agent, by weight. Agitate gently to reduce the amount of air introduced. Allow mixture to set 30 minutes before pouring.
What is a curing agent?
A curing agent is a substance that is used to harden a surface or material. It is typically applied to polymer surfaces to facilitate the bonding of the molecular components of the material.
What is the fastest way to cure PDMS?
Dow Corning Sylgard 184 PDMS can be cured over a range of times and temperatures, spanning ~48 hours at room temperature to 10 minutes at 150ºC. We present an alternate curing method, using an aluminium foil dish, that reduces the curing time from 2.5 hours to 10 minutes.
Does ethanol dissolve PDMS?
In general, highly-polarized solvents (e.g. water, ethanol etc.) and fluorocarbons have low solubility and are well suitable for PDMS microfluidic systems, whereas nonpolar or slightly polar solvents have high solubility, e.g. benzene, pentane etc., and are not compatible with PDMS devices.
What is degree of cure?
The degree of cure of the thermoset polymer is defined as the total heat released up to that point in its cure history with respect to the total heat of reaction for full curing.
What is curing polymer?
In polymerization, curing is a term in polymer chemistry and process engineering that refers to the toughening or hardening of a polymer material by cross-linking of polymer chains, brought about by electron beams, heat or chemical additives.
