Mam my cousin brother work on decorating bangle and epoxy resin is used for the polishing. Prepared epoxy from market is quite expensive so that I want to known the whole process of making epoxy resin from epichlorohydrin and Bis-phenol A at a home if possible . Please also tell about process for making harder if you know. Thank you.
high mechanical strength and lignin replacement rate of lignin-based vitrimers were successfully synthesized by gradually replacing DGEBA with glycidyl ether of lignin. The mechanical properties of the lignin-based epoxy vitrimers can be tuned by different ratios of glycidyl ether of lignin and DGEBA, the Young’s modulus and tensile strength of those vitrimers can reach up to 2.00 GPa and 46.8 MPa, respectively. It's worth noting that the tensile strength and elongation at break were 39.5 MPa and 5.81 % when the lignin replacement rate was 100 %. All the lignin-based epoxy vitrimers exhibit excellent self-healing, reprocessing and shape memory property. The crack widths of the vitrimers were repaired over 80 % in just 5 min at 160 ℃, the tensile strength can reach up to 97 % healing efficiency after being hot reprocessed. The great properties of lignin-based epoxy vitrimers indicate that they can be used as renewable alternatives for bisphenol A epoxy vitrimers.
Warm 24-30°C but don't below 22°C . No dips in temperature during first 24 hrs. Anionic catalyst tertiary amine or imidazole. Or cationic catalyst boron tri fluoride complex can be used.
The term "epoxy", "epoxy resin", or "epoxide" (Europe), α-epoxy, 1,2-epoxy, etc. refers to a broad group of reactive compounds that are characterized by the presence of an oxirane or epoxy ring. This is represented by a three-member ring containing an oxygen atom that is bonded with two carbon atoms already united in some other way.  Hence, the presence of this functional group defines a molecule as an epoxide - where the molecular base can vary widely resulting in various classes of epoxy resins. And they are successful because they offer the diversity in molecular structure that can be produced using the same chemical method.
एपॉक्सी राल को हार्डनर के साथ मिलाएं। मिश्रण अनुपात आमतौर पर 1:1 या 2:1 होता है। उदाहरण में, प्रयुक्त एपॉक्सी का अनुपात 2:1 है। इसे डिस्पोजेबल कप में राल के 2 पंप और हार्डनर के 1 पंप की आवश्यकता होती है। बहुत अच्छी तरह मिलाएं, पक्षों और तल को तब तक खुरचें जब तक कि राल और हार्डनर पूरी तरह से शामिल न हो जाएं। निर्देशों में यह भी शामिल होना चाहिए कि घटकों को एक साथ मिलाने के लिए कितने मिनट। 3
स्पष्ट राल में वर्णक जोड़ने के लिए अभ्रक पाउडर या अल्कोहल स्याही का प्रयोग करें। अगर अभ्रक पाउडर का उपयोग कर रहे हैं, तो राल में थोड़ा सा पाउडर डालें और अच्छी तरह मिलाएँ जब तक कि रंग एक समान न हो जाए। यदि अल्कोहल स्याही का उपयोग कर रहे हैं, तो आप इसे राल में मिला सकते हैं या राल को मोल्ड में डालने के बाद जोड़ सकते हैं।
राल को सांचों में सावधानी से डालें - बेझिझक प्रयोग करें और इसके साथ रचनात्मक बनें। विभिन्न प्रभाव प्राप्त करने के लिए राल डालने के कई अलग-अलग तरीके हैं। एक पोखर तकनीक के लिए, साँचे के केंद्र में थोड़ा सा स्पष्ट राल डालें, फिर ऊपर से अलग-अलग रंगों को एक ही केंद्र के पोखर में डालें। राल बहने लगेगी और सांचे में भर जाएगी। एक दूसरी डालने की तकनीक अलग-अलग रंगों के रेजिन को एक साथ डालना है, जिससे विभिन्न रंगों को एक साथ मिलाने की अनुमति मिलती है। एक तीसरी डालने की तकनीक स्पष्ट राल को सांचे में डालना और शराब की स्याही की कुछ बूंदों को राल में गिराना है। वस्तुओं को राल में जोड़ें, यदि वांछित हो - जैसे चमक, दबाए गए फूल, मोती, पत्ते और बहुत कुछ। 5

I am working one year but not achieve fast drying Epoxy yd128 and curing agent NC541lv use but drying time 2 hours 15 min me rapid curing Karna hai iske liye kya karna chahiye Please Mam reply as soon as possible
CAUTION! Pots of curing epoxy can get hot enough to emit hazardous fumes and ignite combustible materials nearby. Place pots of mixed epoxy in a safe and ventilated area, away from works and combustible materials. Dispose of the solid epoxy mass only after it has completely cured and cooled. Follow federal, state, or local disposal regulations
Depending on the degree of polymerization (n), it may be liquid (n < 1) or solid (n > 1.5). The epoxy polymers can react with different types of chemical group, such as amines, anhydrides, isocyanates, phenol, and others
Typical flexographic/gravure printing inks contain resins, solvents, colorants, and additives. The resins include rosin esters, polyamides, polyurethanes, nitrocellulose, and others. The solvents are often based on alcohols, acetates, glycol ethers, and possibly other solvent classes.
Hello ma'am how can i contact you please tell I got a small question I want to start with some basic chemistry to learn this bondings much better but I'm not able to find the playlist help me please thank you
I will make some videos on it but now you can get some knowledge about periodic property and practical knowledge like titration through playlist in my channel
Why do you mixing language maybe you can use English only or your native language once you mix , it is difficult for those. One who doesn't listen your native language.
Excellent mam,watch from Pakistan,,, knowledge have no boundaries
Good luck 👍
Very well explained!
Thank you share it

Hi mam
What is risk during polymerization reaction of epoxy resin production ?
CAUTION! Pots of curing epoxy can get hot enough to emit hazardous fumes and ignite combustible materials nearby. Place pots of mixed epoxy in a safe and ventilated area, away from works and combustible materials. Dispose of the solid epoxy mass only after it has completely cured and cooled. Follow federal, state, or local disposal regulations

Epoxy resin is plastic or polymer??
It's polymer, polymer broadly devided in to four categories plastic, rubber,fiber and resin.
