What is the curing agent in sylgard 184?

silicone curing agent
Dow SYLGARD™ 184 Clear is a two component, flowable, room temperature and heat cure silicone curing agent with good dielectric properties and flame resistance. Curing agent only. It is to be used with Dow SYLGARD™ 184 Base to form a flexible, encapsulant that is used to protect electrical applications.

What is sylgard used for?

Dow Sylgard 182 is a silicone elastomer used in a variety of applications including general potting, industrial controls, power supplies, connectors, transformers, amplifies, high voltage resistor packs, on solar cells and circuits during processing.

How long does Sylgard 184 take to cure?

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.

Is sylgard PDMS?

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.

How do you prepare a sylgard 184?

Mix the two components thoroughly using a weight or volume ratio of 10:1. Note: The pot life is 2 hours for catalyzed Sylgard 184 at room temperature. It is recommended to vacuum de-air, with a residual pressure of 10-20 mm mercury, which, when applied for applied for 30 minutes, will sufficiently de-air the material.

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. The stronger the molecular bonds are, the harder the material surface is.

What is PDMS material?

Polydimethylsiloxane, called PDMS or dimethicone, is a polymer widely used for the fabrication and prototyping of microfluidic chips. It is a mineral-organic polymer (a structure containing carbon and silicon) of the siloxane family (word derived from silicon, oxygen and alkane).

How can I make PDMS harder?

To make it harder you have to add a curing agent. The most used PDMS is clearly the Sylgard 184. For this PDMS the usual ratio between the curing agent and the PDMS is 1:10 (weight). For specific applications the ratio can be changed to have a PDMS that is softer or harder.

What is the curing agent for epoxy?

Aliphatic amine (Three Bond 2103) is curing agent for epoxy resin ant able to cure at room temperature. The cured resin has excellent properties, and its heat resistance is 100°C. Aromatic amine has been developed to achieve greater heat resistance and chemical resistance than those of aliphatic amine.

Can you add too much hardener to epoxy?

Off ratio: Too much or too little hardener will affect the cure time and thoroughness of the cure. Remove epoxy. Do not apply additional material over non-curing epoxy. DO NOT add extra hardener for a faster epoxy cure!

Is PDMS A plastic?

PDMS is the most widely used silicon-based organic polymer due to its versatility and properties leading to many applications.

Why PDMS is used in microfluidics?

Polydimethylsiloxane (PDMS) has come to be the most widely used material in microfluidic device fabrication due to its many advantages in fabrication ease, physical properties, and economy.

How much silicone is in Sylgard 184 silicone elastomer?

SYLGARD 184 Silicone Elastomer is supplied in lot matched kits consisting of base and curing agent in separate containers. The two components should be thoroughly mixed using a weight or volume ratio of 10:1.

What is the product name of Sylgard elastomer curing agent?
